Special Containment Procedures: SCP-XXXX is to be kept on a pedestal in standard containment chamber at site-73 with the object's owner's manual being stored in Dr. Wagner's office if needed.

When performing test with SCP-XXXX record the number called, a transcript of the call, and if possible, the name of the call recipient. In the event that SCP-XXXX might receive a call, ignore it as it most likely an interdimensional telemarketer. However, this has, so far, only ever occurred once.

Description: SCP-XXXX is a black Western Electric model 500 telephone from the 1950's that is capable of making phone calls to other dimensions. It does not require any form of internet or land line, connection to make calls, but does need to be plugged into an electrical outlet to function. SCP-XXXX also came with an instruction booklet that explains how to set up, and the proper use of SCP-XXXX, in addition to a number for customer support1.

SCP-XXXX was recovered from a thrift shop in ███████, Kansas by agent ██████ ██████ on ██/██/2017. Upon discovery of SCP-XXXX's anomalous properties, agent ██████ purchased the objects and notified the foundation.

So far SCP-XXX has been used to make 43 calls, and on one occasion has received a call. Despite extensive testing, how SCP-XXXX exactly functions is not yet fully known, especially since when opened up the object is no different to a normal model 500 phone. However, it is theorized that it likely utilizes some form of quantum entanglement to communicate.

Addendum-XXXX-02:
The following is an excerpt from page 2 of SCP-XXXX's owner's manual

THANK YOU FOR PURCHASING THE WESTERN ELECTRIC MODEL 500-ID™ TELEPHONE

We here at Western Electric must thank you for purchasing our Model 500-ID™ Telephone!

Now we know what you're wondering, "What does the ID stand for?" Well it's quite simple really, it stands for INTER-DIMENESIONAL! That's right! Using advance phone technology the Western Electric Model 500-ID™ phone can makes calls across dimensions! The possibilities are endless! So what are you waiting for?
**But how do I use it?
Simple, works the same as any other phone! Just put in a number like normal, and if you want it to be inter-dimensional all you have to do is but in a few extra numbers at the beginning. An inter-dimensional phone book has been provided in this booklet on page. 10 and has list of 100 separate dimensions and ID-Codes.

Addendum-XXXX-A: On ██/██/████ testing of SCP-XXXX was authorized. Below is a transcription of the first call made using SCP-XXXX.

Dr. Wagner: Ok, thank you. Now then, what year is it?

[Subject doesn't respond]

Dr. Wagner: Mr. Wozniak, are you still there?**

Sam Wozniak: Is this a prank call?

Dr. Wagner: No sir, of course not. Like I said before, I am helping conduct a scientific study.

[Subject remains silent for a few seconds]

Closing statment: It seems the ID-Code 4564 is for a dimension with a slightly more advance 1870's earth, and were automobiles became mainstream much sooner than they did in our dimension.

Addendum-XXXX-B: The fourth test with SCP-XXXX ended up calling an alternate version of the Foundation, specifically alternate version of the O5 council while they were in the middle of council meeting. O5-2 is the one speaking in the call

Special Containment Procedures: SCP-079-J is packed away in a double-locked playpen in the secured general daycare area at Site-15. Staff who are 1 to 4 years old may have access to SCP-079-J, but must be supervised by a responsible adult while interacting with the object.

ATTENTION ALL STAFF
Supervising staff are not to take pictures during interactions with SCP-079-J… no matter how adorable it is, as much of the staff who are approved to access the object find it demeaning.
